Gamma-linolenic acid is an omega-6 fatty acid with 3 double bonds, compared to linoleic acid, the main source of omega-6, which has only two double bonds.

Gamma-linolenic acid can go on to be converted into dihomgammalinolenic acid, which then becomes arichidonic acid. However, GLA can be shunted into a different pathway to become anti-inflammatory prostaglandins. That shunting occurs when there are sufficient other molecules competing for the enzymes that go to make dihomogammalinolenic acid.....those competitors are omega-3 fatty acids. So, high intake of omega-3 with GLA goes to anti-inflammatory effects.

P.S. Don't you love the name dihomogammalinolenic acid? Only a geek could come up with that one.
